Revising the tooth profile of the female die of an involute gear is often needed in P/M industry. It is very difficult to correct the tooth profile by the software of a slow-feeding wire-cut machine. The tooth profile of an involute gear can be drawn precisely by using the software of EXCEL and AUTOCAD according to the forming principles of the involute. It is more intuitional, convenient and effective to modify the tooth profile.

Sinter-hardening of PM components is an established cost-effective process to produce high strength parts. However, controlling dimensional tolerances is also an important objective while producing sinterhardening components as machining afterwards is relatively difficult and expensive. This study is focusing on a comparative study of various sinter-hardening PM steels and how they perform in terms of strength, ductility and dimensional consistency. PM steels alloyed with different alloying elements based on MPIF standard are compared and the respective performance profiles are presented.
